Abstract

Sodium titanate nanotubes (NaTNTs) are converted into monoclinic TiO 2 (B) nanotubes by rinsing with 0.10 M HCl followed by drying at 573K. As calcination temperature is increased to 673K, these TiO2 (B) nanotubes start to transform into anatase nanoparticles producing a bi-crystalline mixture consisting of TiO2 (B) nanotubes and anatase nanoparticles. The primary particle size of the anatase particles was estimated to be around 10 nm using Scherrer equation. After being promoted with 1% Pt, this bi-crystalline material becomes a very active photocatalyst producing 20% more H2 gas than 1% Pt/Degussa P-25 TiO2 in the photocatalytic dehydrogenation of neat ethanol after 2 h of UV light irradiation.
